To all 'whom it mag/concern: Be it known that'l, JOHN H. Lone, a citizen of the United States7` residing at New the county, of Tuscarawas and State of Ohio, have invented certain newl and useful Improvements nStreet-Sweepers, .of which the followingr is a specification. This-invention relates to street sweepers. One object is to provide a machine for the cleaning of streets,l roadways, and other places, embodying -such characteristics that the dirt will be taken from the bed surface and elevated through the machine for deposit into a removable receptacle carried by the and quickly detached from the machine for umping purposes. v

Another object resides in the provision of a machine of the nature stated embodying in its organizationsimplicity, inexpensiveness, durability and efiiciency.

It is still further designed to provide a machine adapted to be the cleaning of streets, and its construction and arrangement is such that the work ma be accomplished expeditiously'at a minimum of cost, in that ut one operator is necessary.

lit-l1 the above and 4other objects in'view, the present' invention consists in the com# ination and' arrangement ofparts hereinafter more fully described, illustrated in the drawings and particularly pointed out in the appended claims, it being be made n the form, proportion, size an minor details Withoutdeparting from the spirit. or sacriiicin any of the advantages thereof.

n the drawings :-F1gure 1 is aside eleva- Fig. 2 is a longitudinal sectional view. Fig. 3 is a to planA view. Fig. 4 is a transverse sectional vlew through the swee er head. Fig. 5v isa transverse view on t e line B-B of Fig. 3. Fig. 6 is a detailed view of one of the bars on which the front wheels are mounted,'and which are ador lower said- Wheels; Fig. 7 is a detail fragmentary view the lconnection of the guard 23 Referring now7 more particularly to the acthe side bars of the frame of the machine connected at one end by the bar 2A .and intermediate their ends,` by; the

-Mounted upon the side barsl fin- .frame.. This endless convyer is prefera posed bearing boxes 4 in which boxes is journaled the counter-shaft 5 having one end rojecting beyond one of the boxes and provlded with a large sprocket wheel 6 and a smaller s rocket 7 spaced from the wheel 6 by a suita le spacing element 8.

Disposed upon the forward ends of the side bars 1 are the o positely dis osed boxes 9. in which is journaed the brus headv shaft 10 carrying the brush head 11. one endof the blrlush head shaftl() extending beyond one of t e Wheel 12 ixedly securedthereto, lan which vis connected to the' aforesaid large sprocket wheel "6 through the instru-mentality of a chain 13, so that when the counter-shaft is rotated` in a manner hereinafter ex lained the brush head will be likewise rotated.) The brush head in the present instance may be of any desired construction and is provided with' the scraper blades 14 arranged between alternate airs of brush strips 15. operated Vby a person for he re erence character 16 indicates the dri Vwheels of the machine mounted upon y the driving axle 17 mounted vin any suitable manner in the bearing blocks 18 iixed be-. neath the aforesaid side bars 1. Arranged between one of the driving wheelsand the correspondin side bar 1 is a sprocket Wheel 19 connecte to the aforesald small gear wheel 7 through s rocket chain 20, whereby when the dri shaftis rotated the counter-shaft is'oblgld' to rotate.

Mounted within the side bars l and di'- rected downwardly with respect thereto are the side bars -21 and 22 of an elevator frame, the sides 21 and- 22 at their lowerends bel connected by a sheetmetal guard 23, whose ends are secured in the grooves 23 in the the instrumentality of aboxes and having 'one small sprocket under face ofthe shoes 24 at theforward end Y of the 4bars 1 as best shown in Fig. l. This guard y23 ,coperates withthe brush'liead to cause the dirt to be thrown upon the endless conveyer 25 mounted upon the upper and lower shafts 26 and 27 of the conveygr 5' strapped together in any'suitable manner so that it maybe quie 'y removed from the. frame,v and the' upper shaft 26carries a sprocket lwheel 27 whose teeth are designed tofengage in the aforesaid sprocket chain 20 so that as the'driving shaft 1-7 is operated the 'endless apron or conveyerawill travel continuously to receive ther-dirt' lifted by the rush head or by said head and'its scraper ric aforesaid guard 23, the slats 1 by means of the ward end thereof by way of the 28 of the apron the dust and dirt bars and carried thereonto or conveyer preventing fromaccidentally sliding backwards off the l a ron or eonveyer. The groove 23 in the s oes 24 is shallow to permit the guard to lie i close to theground.

Detachably suspended from the side bars hooks 29 is a dust or dirt collecting receptacle 30 designed to`receive the matter carried up the apron or elevator.V When' desired this collecting receptacle may be readily detached fromvthe machine for the pprpose of depositing the dirt in any suitable ace. There are times when it might be dedired to raise or lower the brush head, and for this` urpose l secureupon each bar 1 at the fora plate 31. Each plate is pivotally mounted at its forward end upon the corresponding side bar 1 by means of a suitable pivot 82 (see Fig. 5) and has its opposite end rovided with a slot 33 designed to fit over t e screw 311, with which latter cooperates a nut 35 designed to tighten the-y plate 81 1n its different positions according to the raising or lowering of the front wheels 35 mounted upon the stub shaft 36 of the the invention in brush head upon the street, roadway,

I corresponding 30 understood that the front wheels of the deplate 31 andheld thereon by means of a suitable key. Thus it will be vice are not carried directly by the side bars 1, but that on the other hand they are carried by the plates-31, and byreason of the ivotal mounting of each of the latter at its orwardend and the slot in its rear end, the brush head may be raised or lowered as may be desired. This is an essential feature of that there are times when it is necessary to have heavy pressure of the other place.

or one end, anr

bearings of the machine, but may be readily removed, if desired.

What is claimed is :J-

1.. A street sweeper comprising a frame, a brush head carried by the frame, a driving shaft, a counter shaft, chain and sprocket connections between the drive shaft, the counter shaft and the brush head, a dirt collecting receptacle carried by the frame for cooperation with said conveyer, a plate pivotally secured upon each side of the frame at the forward end of the latter, cach. of said plates having a slot, means connected with the frame and working in the slot of each plate to adjust the latter, a stuli shaft car fried by. each plate, and a wheel carried hy each stub shaft.

2. A street sweeper comprising a frame, a brush head carried by the frame, a driving shaft, a counter shaft, chain and sprocket connections between the drive shaft, the counter shaft and the brush head, a dirt collecting receptacle carried by the frame for co eration with said conveyer, a plate. pivota y secured to each. side of thc frame at the forward end of the latter, a stub shaft carried by each plate, a wheel carried by each stub shaft, and means whereby each. plate and the corres ending wheel may be shifted to adjust the flame toward and away `from the ground.

3. A street sweeper comprising a wheeled frame, a brush head carried by the frame, a conveyer mounted in tl e frame, a collecting receptacle connected with the frame 'for cooperation with the conveyer, means for driving the conveyer, and a combined supporting and adjusting device for each of the front wheels of the machine, each of said devices including a ivoted member having a slot at means engaging the irame and working in each slot of each member, where- The reference character 37 designates a by the Afront wheels may be adjusted toward dust in the use of thema-chine. This guard l has its sides notched, as at 38, to 'fit over the bearings 9 at the lower ends of the bars 1, and by reasonqo'f this engagement vof the ard over the boxes the guard will not become accidentally disengaged from the side vdust guard adapted to prevent the raising of and away from the ground.

In testimony whereof l aHiX my signature, in presence of two witnesses. i
